  "term": "Evaluation data",
  "field": "Chemistry",
  "definition": "A set of observations, also called validation data, kept for judging how well a fitted model predicts; it must be independent of the samples used to build the model by calibration or training. A root mean square error computed on these data is a standard measure of predictive ability. Test data, by contrast, are measurements on unknown samples, and the name is not applied to evaluation data.",
